Cordless Drill vs Impact Driver: Which One Should You Actually Buy First?

If you can only buy one cordless tool, should it be a drill or an impact driver? A clear breakdown of what each does best, where they overlap, and the right pick for most homeowners.

By Mike Reynolds

Walk into any tool aisle and you’ll see two devices that look almost identical: the cordless drill and the impact driver. The marketing makes them seem interchangeable. They aren’t. If you only buy one, picking wrong means a tool that fights you on every job for the next ten years.

After running both side-by-side on actual projects — framing, deck-building, kitchen installs, and fence repairs — here is the honest breakdown.

What each tool is built to do

Drill / driver. A drill rotates a bit at constant torque. Adjustable clutch for delicate work, keyless chuck that holds round-shank drill bits and screwdriver bits. Good at: drilling holes, driving small-to-medium screws, and tasks that need precise torque control (cabinets, hardware, drywall anchors).

Impact driver. An impact driver also rotates a bit, but when it meets resistance it adds rotational hammer-blows (“impacts”) that drive long screws or fasteners with very little effort from your wrist. 1/4-inch hex chuck, no clutch. Good at: driving long deck screws, lag bolts, and stripped fasteners. Bad at: anything that requires controlled torque (it has none — it just hammers until you let go).

The overlap (and where most people get confused)

Both can drive screws. Both accept hex bits. For 95% of small household tasks (mounting a TV bracket, building IKEA furniture, hanging shelves), either tool works. The difference shows up at the extremes:

• Long screws or deck/fence work: impact driver wins by a mile. A drill burns out your wrist after 50 screws; an impact driver stays effortless for 500.
• Drilling holes larger than ¼”: drill wins. Impact drivers can technically drill holes (with hex-shank bits), but vibration, chatter, and lack of clutch make them mediocre at it.
• Cabinets, fine carpentry, soft material: drill wins. The clutch lets you stop driving at exactly the right depth without crushing the workpiece.

So which should you buy first?

For most homeowners doing occasional projects: start with the drill. It is the more versatile general-purpose tool. You can drill holes (which an impact driver does poorly), drive most fasteners, and use the clutch to avoid stripping screws or denting trim.

If your first big project is a deck, a fence, or anything involving 100+ long screws: start with the impact driver. It will save you actual physical pain. A drill for that job is misery.

The “buy both as a kit” shortcut

Most cordless platforms (DeWalt, Milwaukee, Makita, Ridgid, Bosch) sell a 2-tool combo with a drill and an impact driver in one box. The price premium over buying just the drill is usually around 30–40%, and you avoid the awkward year of regret where you only own one.

If you’re already past the “do I want to be the kind of person who owns power tools” stage, just get the combo. You’ll use both.

Quick checklist when buying

• Battery platform first, tool second. Pick a brand and stay with it — every brand has its own battery, and they don’t cross-compatible.
• Brushless motor. Brushless lasts longer and runs cooler. For under $20 more, it’s worth it.
• Two batteries. One charging while one runs.
• 18V / 20V Max class. Don’t bother with 12V unless you’re buying a single-purpose compact driver.
• Skip the “smart” features. Bluetooth, app integration, RPM tracking — a tradesperson uses none of it.

Bottom line

The drill is more versatile; the impact driver is more powerful. Most first-time buyers should choose the drill. Most second-time buyers regret not having gotten the combo upfront. If your first real project involves a lot of long screws, flip those priorities.
